COMBINED CORN-HUSKER AND FQDDER-SHREDDER.

SPECIFICATION forming part of Letters Patent No. 621,505, dated March21, 1899.

Application filed November 15,1897. Serial No. 658,535. (No model.)

in combined corn-huskers and fodder-shredders.

The primary object of my invention is to provide an improvedconstruction whereby the cornstalks are adapted to be fed horizontallyto the rolls and the stalks carried between the rolls in theirhorizontal position, leaving theseveral ears remaining on the rolls tobe stripped of their husks, thereby effecting a great saving of time, asthe stalks can be drawn between the rolls horizontally in a very shortperiod.

An incidental object is the provision of an improved form of feedingdevice which is simple in construction and adapted to insure thehorizontal feeding of the cornstalks and their attached ears.

A still further object contemplated is the provision of improved cuttingand crushing mechanism arranged beneath the rolls and adapted forcutting and crushing the detached cornstalks into short strips orslivers for use as fodder. I

Having the above and other objects in View the invention consists of thedevices and parts, or their equivalents, as hereinafter more fully setforth.

In the accompanying drawings, Figure 1 is a side elevation of theinvention with parts broken away. Fig. 2 is an end elevation.

Fig. 3 is a cross-section on the line 3-3 of Fig.

1 with the side boards 8 removed, and Fig. 4 is a plan view of the rollsand gearing.

Referring to the drawings, the numeral 5 indicates the base of theframe, 6 6 the rearwardly-inclined front standards, and 7 7 the rearstandards. Extending longitudinally of the frame from the front to therear standards are the side boards 8 8. At the ends of the frame,between the respective standards,

are secured brackets similar to 9, which are formed with bearings forthe shafts or end journals of a plurality of rolls. Four of these rollsare shown in the accompanying illustrations of my invention, and saidrolls are arranged in sets. The two rolls of one set are indicated bythe numerals 1O 10 and the two rolls of the other set by the numerals 1111". A space is left between the sets of rolls, so that the inner rollsof the sets will clear each other without contacting, while the surfacesof the two rolls of a set are in close proximity, so as to almostcontact. The extended journal of one of the rolls carries thereon agear-wheel 12, andthis gear-wheel is in mesh with a pinion 13, mountedon a main driving-shaft 14. This shaft has mounted fast on its end twoband-pulleys 15 and 16, respectively, and a fly-wheel 17 is locatedthereon between the two pulleys. The outer wide band-pulley 15 isadapted to receive therearound a driving-belt (not shown) leading fromany suitable source of power, while the other pulleylG is adapted toreceive therearound a crossed belt 18, which belt extends to andaround aband-pulley 19, mounted on a fan-shaft 20, said shaft being journaled insuitable bearings 21 21 and extending into a fan-casing 22. This shaftcarries on its inner end, within the casing, a series of wings or blades23. The perimeter of the casing is provided with an opening 24:, withwhich a conduit or pipe (not shown) may be connected.

The journals at the rear ends of the rolls have mounted thereonintermeshing gears 25. It is obvious that as the gear-wheel13 is rotatedfrom the main driving-shaft the roller on the journal of which said gearis mounted will be rotated, and its rotation, through the intermeshinggears 25, will be communicated to all of the other several rollers.

- The numeral 26 indicates a short shaft on which is mounted a gear 27,somewhat larger than the gears 25 and meshing with one of the end gearsof the series of gears 25. The rotation of this end gear therefore iscommunicated to the gear 27, and this gear 27 is also in mesh with agear 28,.mounted' on one end of a shaft 29, the other end of said shaftcarrying a grooved pulley 30.

ing portions.

The several rolls employed in connection with my improvements may be-ofany desired construction best adapted to perform the functions intended,although the form illustrated in the accompanying drawings is preferred.The front ends of these rollers constitute the receiving ends thereof,while the remaining portions thereof constitute the husk- There arespaces 31 31 between the front receiving portions of the rollers, saidspaces extending from the extremities of said rollers inwardly for adesired distance and gradually diminishing in width toward the innerextremities. These front receiving portions of the rollers are providedwith longitudinal rows of radially-projecting teeth 32, which rows ofteeth alternate with each other longitudinally, the rows of teeth on oneroller of one set entering the intermediate spaces axially orlongitudinally of the other roller as the rollers revolve. The teeth'32, as the corn is fed to the rollers, take hold of the stalks andcarry them between the rollers. The husking portions of the innerrollers 10' and 11' are provided with a number of projectinghusking-pins 33 and the outer rollers 10 and 11 with registeringrecesses 34 to receive said pins as the rollers revolve. The huskingportions of the rolls 10 and 11 are also shown as having secured theretodiamond-shaped nippers 35 35, preferably of steel, which nipperspreferably extend from the inner ends of the receiving portions of therollers lengthwise of the husking portions of said rollers forsubstantially one-half the lengths of said husking portions. The huskingportions of the rollers 10 and 11 are also formed with recesses 36 36,which are so located as to receive therein the projecting edges ofthe'steel nippers as the rollers revolve toward each other. The recesses36. advisably extend throughout the entire length or substantially theentire length of the husking portions of the rollers 10 and 11.

Mounted in the upper portion of the frame proper of the machine is myimproved form of hopper, consisting of the side pieces 37 37 and a frontend piece 38, which connects said side pieces. The lower edges of theside pieces 37 fit within longitudinal boards 39, and the lower edges ofsaid side pieces 37 are beveled or inclined rearwardly to correspond tothe slant of said boards 39 and with the side boards 8 of the frame andthe general declination of the machine from the front to rear, therollers and other parts of the machine being on a gradualslantrearwardly, as clearly shown inthe drawings. The inclined formationof the side pieces 37 of the hopper of course throws the widest portionsof said side pieces toward the rear of the machine. Arranged between andsecured to the side pieces 37 at the rear of the hopper is an inclinedtable 40. The hopper is divided longitudi- 'nally into two divisions bymeans of an archshaped partition 41, said partition being socured at oneend to the inclined table 40 and blades 51.

at its opposite end to the connecting-piece 38. Secured to the topsurface of this partition and extending longitudinally thereof is aknife 42. This knife is preferably in the form of a saw-blade, beingprovided at its upper edge with a series of teeth. The side pieces 37,near their front ends, are provided with elongated slots 43, throughwhich bolts 44 pass and enter the edges of a transverse board 38,forming part of the framework.

Mounted in bearings formed at the upper ends of the standards 7 7 arethe ends of a transverse crank-shaft 45, said shaft being formed withtwo cranks 46 46. Connected to these cranks are arms or pitmen 47 47,which extend forwardly and connect with the side pieces 37 of thehopper, as clearly shown. On one end of the crank-shaft is carried agrooved pulley 48, which is connected up to the pulley 30 by means of acrossed belt 49.

Mounted on the main driving-shaft 14, which is arranged beneath theseries of rollers, is a cylinder 50, said cylinder having projectingradially therefrom a series of cutting- Arranged above the cylinder 50and extending parallel therewith is a beam 52, said beam ha'vingprojecting downwardly therefrom a series of fingers 53. The ends of thebeam 52 are formed with journals 54 54, which have their hearings in theframe, as clearly shown in Fig. 5. The ends of the beam are also formedwith upwardly-extending lugs 55 55. Through these lugs bolts 56 56 passand enter the framework. As the knife-cylind er revolves the bladesthereof are adapted to pass between the fingers 53 of the beam 52. Ifany hard substance, such asiron and the like, should be caught by theblades of the cylinder and carried around into contact with the fingers53, the pressure will have a tendency to break the bolts 56 and themoment these bolts are broken the beam 52 is free to turn on itsjournals, By this provision the strain on the parts occasioned by anyhard substance getting into the cutting mechanism is readily compensatedfor without any serious injury to the machinery.

In the operation of myinvention when the main drive-shaft 14 is rotatedrotation is thereby imparted to the several rollers, as hereinbefore'described, and at the same time rotation is'also imparted to the shaft29 and the grooved pulley 30, carried thereon. The rotation of thegrooved pulley 30 is communicated to the crank-shaft by means of thecrossed belt 49. As this crank-shaft is rotated a reciprocating movementis imparted to the side pieces 37, constituting the hopper, to theextent permitted by the elongated slots 43, through which the bolts 44pass. Not only is a reciprocating movement imparted to said hopper, butat the same time the rear end thereof is given an up-and-down movementbetween the longitudinal inner boards 39. It

will be understood that the movable parts of the hopper are the sidepieces 37 thereof, the inclined table 40, the arch-shaped partition 41,and the knife 42, which are all connected together in the mannerpreviously pointed out. The end board 38 is stationary, and the sidepieces of the hopper slide against the opposite edges thereof to theextent permitted by the elongated slots. The cornstalks'may be depositedin the hopper tied up in the form of a bundle, and are so placed thereinthat the ears of corn are toward the rear end of said hopper adjacent tothe inclined table 40. The longitudinal reciprocation of the hopper willcause the teeth of the knife to act on the cord and out the same. Thebundle will then divide itself into two portions, one portion fallingdown in the space between one side of the arch-shaped partition and oneof the side pieces 37, and the other portion of the bundle will fallinto the corresponding space on the opposite side. The inclined table 40has a tendency to force the cornstalks toward the front end of themachine, and the up-anddown shaking movement imparted to the hoppercauses the cornstalks after they pass into the spaces between thearch-shaped partition and the sides of the hopper to arrange themselvesproperly lengthwise on the rollers. It will be noticed that extendingdown from the sides of the arch-shaped partition are guards 57 57, whichprevent the cornstalks from arranging themselves on thesurfaces of thetwo inner rollers of the series. The moment the stalks come'in contactwith the surfaces of the sets of rollers '10 10 and 11 11' the teeth 32first engage the stalks and tend to pull them into the spaces betweenthe rollers, in the widest portions of the spaces 31, where they aregradually worked down toward the more narrow portions of said spaces.The nippers 35 35 also come into play as the rollers are revolved. Saidnippers during such revolution pass into the recesses 36, and the stalksare thereby necessarily pulled in between the pointsor edges of thenippers and the walls of the recesses, being thereby compelled to make avery short turn. The sharpened edge or point of the nippers then seversthe stalks from the ears, and said stalks are carried between and belowthe rollers. The recesses 36 are preferably continued to the front endsof the rollers, inasmuch as should any portions of the stalk remain onsaid rollers after the nippers have acted the recesses will moreeffectually carry the stalks between the rollers and will also carry thehusksv between the rollers. The ears of corn 'of course slide down therollers and are acted upon bythe huskingpins 33, and thereby stripped oftheirhusks, said husks being carried between the rollers. The ears ofcorn finally slide off the rear ends of the rollers into a suitablereceptacle.

The cornstalks and husks which pass between the rollers are caught bythe knives of the revolving cylinder and carried against the fingers 53of the beam 52, and are thereby cut up or crushed into short lengths orslivers. These short lengths or slivers are deposited upon inclinedplatforms 58 and 59,

respectively. Theinc lined platform 58leads downwardly from the rear endof the ma chine to the fan-casin g, and the inclined platform 59inclines downwardly from the front end of the machine toward the rear,so as to deposit onto the platform 58. The fodder caught by the platform58 is carried into the nessity of feeding loose cornstalks continuouslyto the machine and that instead thereof the stalks can be fed in bundlesand the tying cords automatically severed and the stalks automaticallyarranged and deposited lengthwise onto the rolls. It is also apparentfrom the fact thatthe cornstalks are fed horizontally to the rolls andare carried horizontally between the rolls that an important advantageis gained, as a great saving in time is thereby effected over the moreusual way of feeding the stalks vertically or in an approximatelyvertical line to the rollers, so as to be carried vertically throughsaid rollers.

A further advantage -of my invention resides in the particular form ofcutting mechanism whereby damage or breakage of the parts, owing to hardsubstances getting into the cutting mechanism, is avoided.

While I have herein shown and described four rollers, I do not wish tobe understood as limiting myself to that number, inasmuch as it isobvious that, if desired, only two rollers may be employed, with onlythe necessity of omitting the central partition of the hop: per anddecreasing the width of said hopper to some extent. It is, furthermore,evident that more than four rollers may be employed, as the number ofsets of rollers may be increased in accordance with the widthandcapacity of the machine.

It will of course be understood that the bearings for the journals ofthe-several rolls are yielding, so as to permit them to spread apartsomewhat as the cornstalks are forced therebetween.

What I claim as my invention is.-
